Wireless USB Technical Documents

Wireless USBCV Test Specification(WUSBCV), Rev. 1.0 (.pdf file format, size 476KB)This document contains a list of requirements from Chapters 4, 5, 6, and 7 of the Wireless USB specification.Chapter 8 is covered in separate documents for HWA and DWA.The individual requirements are presented in a section of test assertions.Each assertion is a specific requirement that must be met by a device, host, or wire adapter per the Wireless USB specification.

Wireless USB Device Wire Adapter (DWA) Test SpecificationRev. 1.0 (.pdf file format, size 424KB) This document is the test specification for USB-IF testing of Device Wire Adapter (DWA) products against the Wireless USB Wire Adapter Class.The Wire Adapter Class is described in Chapter 8 of the Wireless USB Specification.The requirements are presented with a series of test assertions.Each assertion is a specific requirement that must be met by a DWA per the Wireless USB specification.Device Wire Adapters are specific implementations of Wireless USB devices, in this respect a DWA must comply with various other test specifications.

These Test Specifications contain test descriptions that provide specific test algorithms and Pass/Fail criteria for some of the assertions.These documents will focus on describing device tests that can be preformed with a standard Wireless USB Host.

EVM Test Procedures for Wireless USB Products

There are three documents for the Wireless USB EVM Test Procedures.These documents are provided as a resource for EVM compliance testing.The EVM Test Procedures are required for the compliance program. Within each, the document for EVM testing outlines the test process for WUSB host and device adapters. Please determine which set of procedures meet your need based on your test equipment choice.

EVM testing is required for ready-to-ship products. Informational EVM compliance testing is first proven by testing the reference designs, proofs of concept and one of a kind prototypes of peripherals, add-in cards, motherboards, or systems. Although not all of the assertions are verified with the Wireless USB EVM Test Tool and procedures, all products are expected to perform within the test criteria outlined within the Test Specification.

USB-IF EVM Test Tools

The EVM Test Tool and Wireless USBCV EVM Test Suite is designed to facilitate the EVM tests. These EVM Test Suites within Wireless USBCV are required in conjunction with the EVM test procedures and EVM Test Tool to perform each of the EVM Compliance Tests. The Wireless USB EVM Test Suites are a part of theWireless USBCVinstallation. Each EVM Test Procedure includes the setup instructions to configure an USB-IF approved EVM Testbed required for compliance testing.

Packet Error Rate Test Document for Wireless USB Products

This document is provided as a resource for PER compliance testing. The PER Test Procedures are required for the compliance program. The document outlines the test process for Wireless USB host and device adapters. PER Compliance criteria is measured in one known good orientation and up to 3 additional orientations operating at the Wireless USB minimum functional effective area outlined by the PER Test Procedures.

Wireless USBCV is provided with a loopback data transfer tool.These test iterations provide results for Tx, Rx, and comparison failures.Noted within this document are specific DUT characteristics or behaviors that effect PER results.Circuit, cable length, antenna construction, along with enclosure/bezel structural, material, and or density changes can influence wireless PER results.External antennas are also subject to the same WUSB adapter design challenges.

PER testing is required for ready-to-ship products. Informational compliance testing is first proven by testing the reference designs, proofs of concept and one of a kind prototypes of peripherals, add-in cards, motherboards, or systems.

USB-IF PER Test Tools

The Wireless USBCV is designed to facilitate the PER tests.These PER Test Suites within Wireless USBCV are required in conjunction with the PER test procedures to perform each of the PER Compliance Tests. The Wireless USB PER Test Suites is a part of theWireless USBCVinstallation. The PER Test Procedure includes the setup instructions to configure an USB-IF approved PER Testbed required for compliance testing.
